What does iodinate mean?
To iodinate a substance is to introduce iodine into it, usually by chemical combination. The term is especially common in chemistry and biochemistry, where iodine may be added as a reagent or attached to a particular part of a molecule. An example is the enzymatic iodination of tyrosine residues within a protein, which can change the protein’s chemical behaviour. Iodination also has important medical and research applications, including the use of radioactive iodine as a tracer for following biological processes. In ordinary discussion, people more often speak of iodizing salt, because adding iodine to table salt helps supply the nutrient and reduce the risk of iodine deficiency. Although “iodinate” and “iodize” overlap, “iodinate” is generally the more technical and reaction-focused expression, while “iodize” is especially associated with food fortification. The word is useful for distinguishing a specific chemical process from the broader idea of treating something with iodine.
verbTo combine a substance with iodine or an iodine compound. In chemistry, it can also refer to introducing an iodine atom or group into a molecule.
- To treat a substance or compound with iodine.
- To introduce iodine into a chemical compound or molecular structure.
"The process uses an enzyme to iodinate selected tyrosine residues in the protein."
"The laboratory iodinated the sample to prepare it for analysis."
"The enzyme iodinates proteins at specific sites, altering their function."
Iodination is how radioactive iodine became a tracer: atoms could be attached to a molecule and followed through a living system.

Etymology of iodinate
“Iodinate” was formed from “iodine” and the suffix “-ate,” following a pattern common in chemical terminology. “Iodine” itself comes from Greek iōdē, meaning “violet,” in reference to the colour of the element’s vapour. The derived vocabulary includes “iodide” and “iodate,” which name different chemical compounds of iodine.

How iodinate is actually used
This is primarily a technical term used in chemistry, biochemistry, medicine, and related fields. In everyday contexts, “iodize” is more common, especially for treating salt with iodine.
